Ulvilan Harjunpään vaaran vuodet 1918-1920 ; kyläyhteisöä erottavat ja yhdistävät tekijät sisällissodasta suurpaloon

Tutkielmani käsittele Ulvilan Harjunpään kylän tapahtumia sisällissodan aikana vuonna 1918, sekä kylän suurpaloa vuonna 1920. Tavoitteena on selvittää miten kaksi erilaista, ajallisesti lähekkäin tapahtunutta tragediaa ovat vaikuttaneet kyläyhteisöön sekä erottavina että yhdistävinä tekijöinä. Tutkimusaineistona käytän pääosin aikalaiskirjoituksia, kuten sanomalehtikirjoituksia ja kunnanhallituksen pöytäkirjoja, mutta myös karttoja ja kuvia, sekä 80-luvulla tehtyjä haastatteluja. Sekundaarilähteinä toimivat erilaiset paikallishistoriaa käsittelevät kirjoitukset, sekä palontorjunnan historiaa ja sisällissotaa käsittelevät tutkimukset. Tutkielman olen toteuttanut käyttäen monia eri metodeja. Pääosassa ovat olleet historiallinen sekä mikrohistorian metodi, kuin myös havainnointi ja muistitietotutkimus. Loppupäätelmänä todettakoon, että kaksi erilaista tragediaa ovat vaikuttaneet syvästi sekä yhteisön itsetuntoon, että suhtautumiseen toisiin ihmisiin. Taustalla vallitsevat poliittiset erimielisyydet, luokkaerot, uskonnollisuus ja vanhat kaunat sekä katkeruus. Jossain määrin menneisyyden taakka vaikuttaa vielä nytkin kylän yhteisölliseen ilmapiiriin, vaikka se ei olekaan enää kovin selkeää.

Direct mass measurements of (68)Se and (80)Y

The masses of neutron-deficient nuclides near the N=Z line with A=64-80 have been determined using a direct time-of-flight technique which employed a cyclotron as a high-resolution spectrometer. The measured atomic masses for (68)Se and (80)Y were 67.9421(3) u and 79.9344(2) u, respectively. The new values agree with the 2003 Atomic Mass Evaluation. The result for (68)Se confirms that this nucleus is a waiting point of the rp-process, and that for (80)Y resolves the conflict between earlier measurements. Using the present results and the 2003 Atomic Mass Evaluation compilation, the empirical interaction between the last proton and the last neutron in N=Z nuclei has been revisited and extended.

Antiviral and antiparasite properties of an L-amino acid oxidase from the Snake Bothrops jararaca: Cloning and identification of a complete cDNA sequence (Retracted article. See vol. 80, pg. 288, 2010)

L-Amino acid oxidases (LAAOs, EC 1.4.3.2) are flavoenzymes that catalyze the stereospecific oxidative deamination of an L-amino acid substrate to the corresponding a-ketoacid with hydrogen peroxide and ammonia production. The present work describes the first report on the antiviral (Dengue virus) and antiprotozoal (trypanocidal and leishmanicide) activities of a Bothrops jararaca L-amino acid oxidase (BjarLAAO-I) and identify its cDNA sequence. Antiparasite effects were inhibited by catalase, suggesting that they are mediated by H(2)O(2) production. Cells infected with DENV-3 virus previously treated with BjarLAAO-I, showed a decrease in viral titer (13-83-fold) when compared with cells infected with untreated viruses. Untreated and treated promastigotes (T. cruzi and L. amazonensis) were observed by transmission electron microscopy with different degrees of damage. Its complete cDNA sequence, with 1452 bp, encoded an open reading frame of 484 amino acid residues with a theoretical molecular weight and pl of 54,771.8 and 5.7, respectively. The cDNA-deduced amino acid sequence of BjarLAAO shows high identity to LAAOs from other snake venoms. Further investigations will be focused on the related molecular and functional correlation of these enzymes. Such a study should provide valuable information for the therapeutic development of new generations of microbicidal drugs. (C) 2008 Elsevier Inc. All rights reserved.

Benefits of the Intermittent Use of 6-Mercaptopurine and Methotrexate in Maintenance Treatment for Low-Risk Acute Lymphoblastic Leukemia in Children: Randomized Trial From the Brazilian Childhood Cooperative Group Protocol ALL-99

Purpose To describe event-free survival (EFS) and toxicities in children with low-risk acute lymphoblastic leukemia (ALL) assigned to receive either continuous 6-mercaptopurine (6-MP) and weekly methotrexate (MIX) or intermittent 6-MP with intermediate-dose MTX, as maintenance treatment. Patients and Methods Between October 1, 2000, and December 31, 2007, 635 patients with low-risk ALL were enrolled onto Brazilian Childhood Cooperative Group for ALL Treatment (GBTLI) ALL-99 protocol. Eligible children (n=544) were randomly allocated to receive either continuous 6-ME/MIX (group 1, n 272) or intermittent 6-MP (100 mg/m(2)/d for 10 days, with 11 days resting) and MIX (200 mg/m(2) every 3 weeks; group 2, n = 272). Results The 5-year overall survival (OS) and EFS were 92.5% +/- 1.5% SE and 83.6% +/- 2.1% SE, respectively. According to maintenance regimen, the OS was 91.4% +/- 2.2% SE (group 1) and 93.6% +/- 2.1% SE (group 2; P=.28) and EFS 80.9% +/- 3.2% SE (group 1) and 86.5% +/- 2.8% SE (group 2; P=.089). Remarkably, the intermittent regimen led to significantly higher EFS among boys (85.7% v 74.9% SE; P=027), while no difference was seen for girls (87.0% v 88.8% SE; P=.78). Toxic episodes were recorded in 226 and 237 children, respectively. Grade 3 to 4 toxic events for groups 1 and 2 were, respectively, 273 and 166 for hepatic dysfunction (P=.002), and 772 and 636 for hematologic episodes (P=.005). Deaths on maintenance were: seven (group 1) and one (group 2). Conclusion The intermittent use of 6-MP and MIX in maintenance is a less toxic regimen, with a trend toward better long-term EFS. Boys treated with the intermittent schedule had significantly better EFS.

Compound 48/80 induces endothelium-dependent and histamine release-independent relaxation in rabbit aorta

Compound 48/80 (C48/80) is a synthetic condensation product of N-methyl-p-methoxyphenethyl am me with formaldehyde and is an experimental drug used since the 1950s to induce anaphylactic shock through histamine release. This study was carried out to further elucidate the mechanism by which this drug induces nitric oxide (NO) release. Our specific goals were: (a) to verify if C48/80`s relaxation occurs through the stimulation of histamine receptors; (b) to evaluate the endothelium-dependent relaxation induced by C48/80; (c) to identify NO as the endothelium-relaxing factor released by C48/80; (d) to identify the NO synthase (NOS) responsible for NO release; and (e) to verify if the relaxation induced by C48/80 is calcium and cyclic guanidine monophosphate (cGMP) dependent. Rabbit aorta segments, with and without endothelium, were suspended in organ chambers (25 ml) filled with Krebs solution maintained at 37 degrees C, bubbled with 95% O-2/5% CO2 (pH 7.4). Phenylephrine was used to contract the segments. Other protocol drugs included H-1- and H-2-receptor antagonists, cyclooxygenase, NOS, guanylyl cyclase and phospholipase C (PLC) inhibitors. Endothelium-dependent relaxation induced by C48/80 was also studied in calcium-free Krebs solution associated with a calcium chelator. In summary, our investigation demonstrated that the C48/80 vasodilating action: (a) does not depend on H-1 and H-2 histamine receptors; (b) is NO endothelium-dependent; (c) is dependent on the endothelial constitutive NOS (NOS-3) isoform activation; (d) is cGMP-dependent; and that NOS-3 activation by C48/80: (a) is independent of PLC up to 25 mu g/ml and (b) is partially dependent of this lipase in higher doses.
